Tell Me Why is a video game created by the same people who made the 2015 game Life Is Strange. It features a brother and sister duo who try to get to the bottom of their mom's death. The brother is a gay trans man, and he's also voiced by a trans man (very rare). His being trans isn't the whole plot of the story, but there are many moments where it is relevant in his journey. It's a good balance of the two. It's a dialogue/cutscene heavy episodic adventure game. If you've played Life Is Strange, the play style is similar.

This video game has a great storyline and is what I consider good representation. Highly recommend playing it.
